I got my files from phils walkthroughhttp://www.e90post.com/forums/showthread.php?t=588311

I created a VM using VMWare. You can also use the Win7 VM for XP. I copied the folders in the zip to my c: in XP then followed the instructions in the NCS_DIY.pdf which you can find in multiple places. I used the one stop cable with the driver on phils page. I didnt update my daten files. I used v41 included in the zip above because I had issues with newer version on my 2007 335i
